Fast physical optics method for 2D rational bézier curves

Abstract:

This letter shows a fast technique to compute the physical optics (PO) integral of a rational Bzier curve. The algorithm is based on the path deformation technique. Good numerical results in terms of CPU time and accuracy are obtained. © 2006 IEEE.
